Description of changes

Updating to the latest release 0.6.0 and switching to the currently actively maintained fork from dreamcat4.

The changelog to the latest release can be found here although the version currently available seems to be much older.

The fork from dreamcat4 seems to be the currently active fork of this project and sees feature updates as well as fixes for decade-old bugs. It would be nice to have that available in nixpkgs.
